auf, indem die Wände des Mischers leicht verkleben, den Betrieb stören und oft gereinigt werden müssen.by slightly gluing the walls of the mixer, the Interfere with operation and have to be cleaned often.

Die Erfindung stellt sich zur Aufgabe, ein Verfahren und eine Vorrichtung zur Ausübung desselben zu schaffen, das die genannten Nachteile vermeidet, wirtschaftlich ist und eine gute Mischung gewährleistet.The invention has for its object to provide a method and an apparatus for practicing the same, which avoids the disadvantages mentioned, is economical and ensures good mixing.

Die Lösung bringt das erfindungsgemässe Verfahren, das darin besteht, dass man das schüttbare Gut über einen Verteiler zuführt, aus dem es in Form eines hohlzylindrischen Stromes in freiem Fall herunterrieselt und während des Fallens au:s mindestens einer Düse mit der flüssigen Komponente besprüht wird.The solution brings the inventive method, the consists in feeding the pourable material through a distributor from which it trickles down in free fall in the form of a hollow cylindrical flow and spraying the liquid component while falling from at least one nozzle.

Bei sehr kleinen Durchflussmengen genügt eine zentrisch im herunterrieselnden Strom angeordnete Sprühdüse, die die flüssige Komponente von innen her in den hohlzylindrischen Strom sprüht. Bei grösseren Durchflussmengen wird man den herunterrieselnden Strom zusätzlich oder ausschliesslich von aussen her aus mehreren Sprühdüsen mit der beizumischenden flüssigen Komponente besprühen. In the case of very small flow rates, a spray nozzle arranged centrally in the trickling stream is sufficient, the the liquid component sprays into the hollow cylindrical stream from the inside. With larger flow rates If the stream trickling down is additionally or exclusively from the outside from several spray nozzles spray with the liquid component to be mixed.

Nur für sehr kleine Durchflussmengen von schnittbarem Gut genügt eine einzige, so angeordnete Sprühdüse. Damit aber auch grosse Durchflussmengen bewältigt werden können, sind an der Wand des Gefässes mehrere Sprühdüsen kranzförmig und in verschiedenen Höhenlagen H]_ H4 angebracht. Auf dem Niveau H^ sind drei Düsen 31 je um 120° versetzt am Umfang des Gefässes angebracht. Der Sprühwinkel 06 ist kleiner als der Winkel zwischen den von der betreffenden Düse ausgehenden Tangenten an den hohlzylindrischen Strom S des herunterrieselnden Schnittgutes, damit die beizumischende Flüssigkeit nicht an die gegenüberliegende Gefäss-Innenwand gelangt und dadurch den Betrieb des Beimischgeräts stören würde. Damit aber trotzdem der herunterrieselnde Schüttgut- · strom überall benetzt wird, sind die drei Sprühdüsen 32 auf dem Niveau H2 umfangsmässig um 60° gegen die Düsen 31 versetzt. Die Düsen 33 auf dem Niveau H 3 liegen senkrecht unter den Düsen 31 und die Düsen 34 auf dem Niveau H4 liegen senkrecht unter den Düsen 32.Only for very small flow rates of cutable A single spray nozzle arranged in this way is sufficient. But so that large flow rates can also be managed several spray nozzles are on the wall of the vessel in a ring and at different heights H] _ H4 appropriate. There are three nozzles 31 at level H ^ each offset by 120 ° attached to the circumference of the vessel. The spray angle 06 is smaller than the angle between the tangents an emanating from the relevant nozzle the hollow cylindrical stream S of the trickling down Cut material so that the liquid to be mixed does not reach the opposite inner wall of the vessel and this would disrupt the operation of the admixer. So that the bulk material trickling down current is wetted everywhere, the three spray nozzles 32 are circumferentially at the level H2 by 60 ° against the Nozzles 31 offset. The nozzles 33 on the level H 3 are perpendicular to the nozzles 31 and the nozzles 34 on the Levels H4 lie vertically below the nozzles 32.

Eine Höhenverstellung des Verteilers 20 erlaubt die Durchflussmenge des Schüttgutes einzustellen und dem Betrieb anzupassen. Wird der Verteiler nach oben verschoben, wird der ringförmige Spalt zwischen dem Teil und dem Verteiler 20 enger und es rieselt weniger Schüttgut pro Zeiteinheit in das Beimischgefäss hinein.A height adjustment of the distributor 20 allows the flow rate of the bulk material to be adjusted and the Adjust operation. When the manifold is moved upwards, the annular gap between the part becomes and the distributor 20 closer and less bulk material trickles into the admixing vessel per unit of time.

Beim Betrieb des Fallstrom-Beimischers wählt man eine Einstellung der Durchflussmenge pro Zeiteinheit, die einen kontinuierlichen Durchfluss erlaubt. Dementsprechend wird auch die Zufuhr des beizumischenden Fluidums eingeregelt. Bei kleinen Durchflussmengen genügt es womöglich nur die zentral angeordnete Düse 30 zu verwenden. Bei grösseren Mengen wird man zusätzlich oder ausschliesslich die Düsen 31 und 32 in Betrieb nehmen und je nachdem auch die Düsen 33 und 34.When operating the downdraft admixer, you choose one Adjustment of the flow rate per unit of time, which allows a continuous flow. Accordingly the supply of the fluid to be mixed is also regulated. With small flow rates it may be sufficient to use only the centrally arranged nozzle 30. For larger quantities, one will also or only put the nozzles 31 and 32 into operation and, depending on the case, also the nozzles 33 and 34.

Da der 3?allstrom-Beimiseher keine bewegenden Teile enthält und keine motorische Antriebaquelle wie sie ein Trommelmischer benötigt, ist sein Betrieb wirtschaftlich. Wie bereits beschrieben, ist der Beimischer für kontinuierlichen Betrieb geeignet.Because the 3? All-current accessory does not contain any moving parts and no motorized drive source like them requires a drum mixer, its operation is economical. As already described, the mixer is suitable for continuous operation.

In der Wand des Gefässes sind mehrere Kränze von Düsen (31,32,33»34) in verschiedenen Höhenlagen (H1 - H,) angebracht, deren slbührichtung radial nach innen auf das herunterrieselnde Gut gerichtet ist.For the continuous mixing of pourable, floury or granular goods with liquid components, a vessel (10) is used, into which the pourable material is fed in at (13) above. A distributor (20) distributes the still dry material so that it trickles down the vessel in the form of a hollow cylindrical stream. During the free fall it is sprayed with the liquid to be admixed from one or more nozzles (30-34). A nozzle (30) is attached under the distributor (20) and can spray the flowing down stream from the inside. In the wall of the vessel, several rings of nozzles (31,32,33 »34 ) are attached at different heights (H 1 - H 1), the direction of which is directed radially inwards towards the material trickling down.
